To dream of a princess represents an aspect of your personality that is powerful because they are viewed as being too perfect, beautiful, or impressive. You or someone that feels that there is nothing wrong with them. Too good or too beautiful to be bothered with problems. Always getting your way because you are special.
Negatively, a princess may reflect selfishness, vanity, being spoiled, or being too demanding. You or someone else that thinks they are too perfect to "get their hands dirty" or do things for themselves.
Example: A teenage girl dreamed of being a princess. In waking life she wanted a boyfriend, but felt that she was too special to be an average boy. Being a princess in the dream may have reflected her feelings about herself being special and deserving to be picky.
